The Tire Size Converter performs tire size conversion from the inch tire size (English/Standard/Imperial measuring system) to the metric tire size and the other way around. Besides the exact tire size conversion from one system of measurement to another, calculator displays adequate actual/real tires with the dimensions which are closest to the calculated tire size, if such exist. The Converter also shows, for the real tire, its dimensions: tire diameter, tire width, sidewall height and the difference between that tire and the original tire.
